A top-ranked town for the quality of its life, famous for its cafés and pastries, Vienna is host to many major international organizations such as the United Nations and OPEC. Vienna International Airport (Flughafen Wien-Schwechat) is located 18 km (11 mi) southeast of central Vienna. The Vienna S-Bahn S7 (from Floridsdorf Station) and S8 (reverse direction) line stops at the airport. The more expensive CAT (City Airport Train) connects the airport directly to the Wien Mitte station close to the city center.
